One of my lead screws has developed a fair bend, and it is badly impacting my prints

So I need at least a new lead screw, but I don’t want to have to replace again in 6 months.

Has anyone used the stepper motors with inbuilt lead screws? What has been your experience?

Either that or any other suggestions?
I could use one of those anti z wobble parts from thingiverse but​ I don’t love that idea, or @ant0ny and I discussed moving to a tevo Tarantula style z motor set up.

I was going to do the Tevo style on the new printer on my desk… a OpenBuilds 300x300x300 (just a copy of the 500x500x500 I recently finished) but I decided I am going to do Dual Independent Extruders instead.

The issue I had with the Tevo style is you need to build the printer around a GT2 Continuous Belt Loop… I tried to join a GT2 belt and it was a fail and that was as far as i got. The Belt loops have all of a sudden become easier to get now and much bigger like over 1m but there is not enough hours in the day.

NOTE: X-MOTOR.STL and X-IDLER.STL are made for 22mm spacing
UPDATE 15.5.2016
moved X-stepper mount point 5mm to left for 21mm version (X-MOTOR_21mm_WIDER.STL)
UPDATE 14.2.2016
made parts with 21mm spacing for Geeetech i3 pro c
UPDATE...

Ahhh MazaaFin that takes me back to my Geeetech Acrylic i3… nice guy I contributed a bit for the Geeetech flavor.

hey have you seen the sub $300 Anet and Tevo printers… they get around the Dual - Single Z motor by not having a second motor. They counter lever the Xaxis from one side relying on the strength and accuracy of the extruded aluminum.
